I would guess that Japanese WWII rifle is an Arisaka Type 33 or Type 99. However, I thought those were all chambered in a 6.5 X 50 caliber, not 7.65. But I could be wrong. Thousands of those guns made it back to the U.S. after the Japanese surrendered, so there is very little monetary value to this gun. You could 'sporterize' it and use it for a deer rifle, though.
Can't help you with the other two guns.
